My lights are off so it looks like I have to experience darkness for a few days, it's been a long time since I bought this lamp about 1 year ago. And now the engine is not strong and the lights are off, it still looks good but this small component can't last long if it is continuously used. And I was forced to buy another lamp with the same brand because the lighting was quite good, hopefully it can arrive quickly so I can replace the old one.
